User Acknowledgement

By accessing NASA ICESat data, the data user acknowledges their understanding that the data have certain limitations in accuracy and definition, which have primarily resulted from problems with the GLAS instrument. Continuing improvements in the calibrations and product definitions are in progress and will be reflected in future data releases. The user should review the statements on product calibrations and accuracies in ICESat/GLAS Data Releases, and consider the calibration issues in any scientific interpretation or other use of the data. Users are requested to report their findings about data quality to NSIDC User Services, to be forwarded to ICESat/GLAS Science Team, for information and comment before publication or reporting elsewhere.

See ICESat Science Investigator-led Processing System (I-SIPS) Release Information for additional details.
